cmap_iter_init - Initialize iterator for keys stored in CMAP
#include <corosync/cmap.h> cs_error_t cmap_iter_init (cmap_handle_t handle, const char *prefix, cmap_iter_handle_t *cmap_iter_handle);
The cmap_iter_init function is used to initialize iteration of all keys with given prefix. The handle argument is connection to CMAP database obtained by calling cmap_initialize(3) function. prefix is string, and every returned key must have name with given prefix. This variable can also be NULL (or empty string) and then all keys are iterated. cmap_iter_init is used only for initialize context for future cmap_iter_next(3) calls and handle needed for that function is returned in cmap_iter_handle variable. When you have finished iteration over objects, call cmap_iter_finalize(3) function to free up memory associated with iteration.
This call returns the CS_OK value if successful. If there are no items with given prefixes, CS_ERR_NO_SECTIONS is returned.
